Hello my fiance has been trying to start breeding leopard geckos and she has been having a hard time getting started. She finally has gotten a pair of eggs. Unfortunately they are attached together and I do believe the one is infertile as it is a straight yellow color. Where as the other one looks like this. I have candled chicken eggs before and know that veins are a good sign. I guess we are just curious if this looks like it is progressing as a healthy egg. Thank you for your time.
